Description
Technical field
The utility model belongs to solution processing equipment, and in particular to a kind of processing unit for landfill leachate.
Background technique
Landfill leachate is the waste water generated in garbage loading embeading or interim stacking process, and water quality has high COD, and (chemistry needs
Oxygen amount, Chemical Oxygen Demand), high salt, high ammonia nitrogen, high heavy metal the features such as, and can be with landfill yard rubbish
It fills the time limit that ingredient, seasonal climate, landfill yard use and changes, be a kind of more intractable high concentrated organic wastewater.Mesh
Preceding country has put into effect the related discharge standard to landfill leachate treatment, has also come out correlation engineering design guidelines, according to for many years
Engineering practice, mainly use two kinds of processing routes at present, one is using two-stage DTRO technique, and one is that biochemistry+film is raw
Object reactor (MBR+NF+RO) technique, in certain areas since percolate concentration is especially high, process above even can not all be handled
In the case where operation, also there is the method for directly taking evaporation and concentration or burning.
The first two technique all due to using membrane technology, has the film concentrate of substantially about 20-30% to need into one
Step processing, it is generally the case that most techniques for using recharge for refuse landfill.But it is percolated returning for concentrated liquor
If filling that operation is lack of standardization or rainy season etc. all may cause the concentrate of recharge and flow back into leachate equalization basin, so that diafiltration
The COD and salt concentration of liquid are increased, and so as to cause the raising of film device operating pressure, rate of recovery decline, cleaning frequently, or causes
Biochemical system is unable to run, into vicious circle.Therefore need to the further minimizing of existing diafiltration concentrated liquor or into
The concentration disposition of one step, so it carries out concentrate zero-emission and is placed with the urgent market demand.
Now for the minimizing disposition of percolation liquid membrane concentrate, multifunctional evaporating equipment, MVR technique is used to set in the market

There is secondary pollution；4) due to salt content height, evaporating temperature is high, therefore more demanding to equipment material.For submersible burning work
It is that burning forms the side of thermal energy evaporation directly in evaporator using imflammable gas (such as biogas or natural gas) for skill
Formula, advantage are that the concentration that is that direct heat transfer can evaporate is higher, but is limited by the influence of energy-provision way, can only have it is flammable
It is just implementable in the case where gas, and in the case where no biogas stable supplying, it can be high using the energy consumption of natural gas.Thus
As it can be seen that proposing a kind of recycling heat energy and do not need to use MVR technique is for landfill leachate evaporation concentration equipment
One of urgent problem to be solved.
